In this chapter, you learned the concept of validation and saw how to enable Bean Validation in Spring MVC for form processing. We also learned how to set up a custom validation using the extension capability of the Bean Validation framework. After that, we learned how to do cross field validation using Spring validation. Finally, we saw how to integrate Bean Validation and Spring validation together.

In our next chapter, we will see how to develop an application in RESTful services. We will be covering the basic concepts of HTTP verbs and will try to understand how they are related to standard CRUD operations. We will also cover how to fire an Ajax request and how to handle it.
